Application filed December 10, 1925, Serial No. 74,586, and in (treat-Britain November 3', 1924;

This invention relatesv to the means for beating up. the pile forming material in the weaving of fabrics of the kind in which the pile forming yarns, or tufts are inserted tion of the weft or wefts constituting the binding weft after coming into osition across the fell of the fabric, and in front of the row of downward hanging tufts, may be beaten up before the tufts are turned up and the remainder of the weft is beaten up. For this purpose I provide (in addition to the usual layhereinafter referred to as the main lay) a supplementary lay having its v own cams and Operating levers for producing the requisite rising and falling and beat-up movements.

' I find my invention to be superior in "that it is applicable to looms of any width-the support or supports of the supplementary lay being always within the width of the loo1nand it does not involve needless sacrifice of time in each cycle, this beinga valuable consideration. My invention is furthermore distinguished byits simplicity and compactness.

By adopting the present improvement a considerable saving of pile forming material can be effected owing to the weft being brought into close alignment with the fell and an appreciable increase in production obtained in a given time, owing to the short-. ness of the time interval between thesupplementary and the main beat ups, the first. r of which as mentioned, acts only upon part of the weft-s supplied by one insertion, whilst the remainder is beaten up immediately afterwardsby the main lay. But the first (i. e. supplementary) beat up is done not only in the minimum interval of'time,

but in such a thorough manner, owing to its general design and that of its controlling mechanism, as to ensure that it shall always beat the binding wefts close to the fell no matter how wide the loom may be.

In order to explain mypresent invention clearly, I will referhereinafter to. the ac-..

The s ame letters of reference repeated in.

the several figures indicate the same or correspond ng features. I

Referring to the accompanying drawings,

I provide in addition to the main or ordinary lay a a supplementary lay 0 whose dents are preferably the Same in number as they are in the main or ordinary reed b. The dents d which collectively form the sup.- plementary reed .areheld and spaced apart in slits 6 cut in a base or holder conveniently formed by metal plates or strips f lying along the back and front of the-reed or dents (Z at their lower ends, the plates and dents cl being soldered or otherwise fas ten-ed together. These plates f extend below the lay 0 by bolts 9, the bolt holes being slotted to provide lateral adjustment to enable the reed d to be brought into register with the spaces between the'warp thr d 7 The lay 0 carries lugs h h which are hinged to short radial j mounted on a bearing shaft k extending across the loom,

said radial arms j and are operated by cams 80 the ends of the dents (Z and are secured tov a working on the lower front shaft 0 which shaft is also well known on the double needle loom.

The beating up motion of this supplementary or special lay 0 is operated from the said lower front shaft 0 by a cam or earns 39 acting upon the lay 0 through an extension or extensions solidly fastened underneath the latter in the form of a lever or levers 9 having a roller 7* on the lower end'of same.

The lugs it it through which the rising and fallingof the special lay is performed can readily be located at any desired'part of the length of the lay and more than two can be employed, if desired. The same remark applies also to the lever g. which may be duplicated at other points. Thus the stresses set up against thespecial reed d and lay a owing to thecounter pressure of the fell of the fabric are distributed in such a manner as to prevent them from bending, which would be inevitable if the lay 0 were supported only at its two extremities. Furthermore, the attachment of the lugs 72 and levers gas described will itself increase the rigidity of the lay 0. p

This additional lay a works-preferably in combination with the placers as specified in my Patent No. l,341,4l17,but it is not limited to this combination.

comb W rises to turn up the ends of the tuft V yarns, whereupon the main lay 04 moves to its furthermost position, while the supplementary lay cmoves a little further from the fell, and below the sheds formed by the heddles.

The wefts T, B are then inserted by the needles passing in and out of the sheds and on their complete withdrawal the placers mentioned in my said patent come into operation asjmay be required for the various weaves.

' When the said placers have brought forward to the fell the necessary portions of wefts T, B, the supplementary reed cl rises up in the spaces between the warp threads,

and behind the weft threads operated on by the placers, but which owing to the distance between theplacers have not been moved towards the' fell sufficiently.

When the supplementary reed (Z has been raised up to a suitable height through the warp threads, it is moved forward towards the fell and lowered at the same time so that the tops of the dents of'the reed (Z are in front of theprevious line of wefts. As

The weave illustrated in Figure 3 is of the known type comprising active warps L and a dead warp D. The weft threads are indicated by 'l and B, the former being the top wefts (or those lying upon the top of the dead varp 1)) and the latter the bottom wefts (or the wefts which are below. the said warp The pile yarns or tufts are denoted by '31 and consist of U-shaped loops which are caught and held bound by top wefts T. This kind of weave is given by way of illustration in Figure 3 and is not a it of the presenti'nvention. The method or inserting the "pile yarns Y is well known in connection with Axminster looms and need not, therefore,'be described. The fabric cannot conveniently be illustrated excepting on the large scale in Figure 3 in which, for the sake of clearness, the fabric is shown spread out upon the breastplate s and is seen to consist of the warps LDL, the wefts TB and the tufts Y. I When thesewefts and tufts are beaten up, they become compacted into the fabric, only the pile material Y being visible upon the tread or upper surface.

I claim:

l. In a 100111 of the character set forth, means for binding a row of tufts which are inserted in two sheds simultaneously, means for beating up the wefts prior to the insertion of said tufts, and a main lay for beat ing up the later inserted wefts. I i

- 2. in a loom for weavingtufted fabrics operating to cause the pile forming yarns or tufts to be inserted between the warp threads and then boundin bybeing partly doubled about the wefts', a supplemental lay for beating up a portion of the weft before remaining portion thereof is beaten up,

means for binding a row of tufts between up some of the Wefts, such lay having. the two sheds, means for beating up the Wefts same number of dents as the main lay, means placed prior to the insertion of the said tufts, for folding the tufts about the Wefts, and a 10 and means associated with the main lay for main lay for beating up the Wefts. 5 beating up the wefts. In testimony whereof I have signed this 4. A 100111 for Weaving tufted fabrics prospecification. vided With a supplemental lay for beating ARTHUR DAVIS.
